I am following these commands to debug my app
Inside index.js
const debug = require('debug')('app:start')
debug('debugging the app... Yup!')
Inside Terminal
set DEBUG=app:start // inside terminal
nodemon index.js // inside terminal

Answer 1

Issue was very silly that I was running these two commands in different terminals that cause the problem
set DEBUG=app:start // inside terminal
nodemon index.js // inside terminal
be sure to run these commands in the same terminal.
Hope this will save time for someone.
